Muscle Tech is one of the biggest supplement companies around, as such it is seen as a given that their natural testosterone booster will be as high in quality as the rest of their well-respected range of supplements.

But is this the case?

In this article we will be taking a look at Muscle Tech’s Test HD natural testosterone booster, and we will help you to decide whether this particular product is up to scratch.

Quick Review: Test HD is a actually a pretty good testosterone booster.

MuscleTech The Company

Muscle Tech is a Chinese-owned Canadian supplement company that has been around for quite a while.

They are well-known and have earned their customers’ trust after years of high-quality supplements.

Being a big company doesn’t guarantee that your natural testosterone booster will be amazing though, but bigger companies are often easier to trust, have better customer service (in case the product doesn’t work etc), and can usually afford to charge less.

We’ll first take a look at Muscle Tech’s claims about Test HD, then we’ll take a look at the ingredients list, before examining the customer reviews, and finally giving you our views on whether the product is worth your cash.

MuscleTech Test HD Claims

Test HD by Muscle Tech has only two claims, the first is that taking it will increase testosterone levels (both total testosterone and free testosterone) within seven days.

The second claim is to increase energy by raising ATP levels in the blood within 15 days.

What’s good about this company is that they have avoided the common crime of listing several benefits that are all connected.

Most companies tend to claim increased testosterone as one benefit, and then claim increased muscle size, reduced body fat etc … as other benefits.

When in fact they are all benefits caused by the initial increase in testosterone.

Test HD Ingredients List Review

The first good thing about Muscle Tech’s ingredient list is that they have provided the dosages for each individual ingredient.

Complete transparency in their product is great news for us as it makes reviewing Test HD a lot easier, and it shows that they have faith in their product’s effectiveness.

Too often supplement companies do everything they can to disguise the dosages of their ingredients.

We’ll take a look at each ingredient and ascertain whether they can increase testosterone or not.

Calcium (48mg): We’re not sure why calcium is present in this supplement, most people easily hit their recommended daily allowance of calcium through diet – which is a better way to absorb calcium in any case. A 2009 study by Cinar et al found that 35mg of calcium per kg bodyweight did not significantly increase testosterone [1]. Overall, we would say that there is potentially a small chance that calcium could increase testosterone but there is more evidence that it doesn’t.

Zinc (7.5mg): It really is a surprise that more natural testosterone boosters that are aimed at gym goers (rather than the elderly) do not contain zinc as a main ingredient. Being deficient in zinc has been shown to reduce testosterone, and what is a common cause of zinc deficiencies? Lots of exercise. Now, this does not mean that zinc increases testosterone. It just means that it can help restore testosterone in men that are deficient in zinc. A study on elite athletes who were performing exhaustive exercise found that taking oral zinc prevented the inhibition of the thyroid, and protected testosterone levels [2].

Tribulus Terrestris (250mg): Increases libido, improves erections, may lower cholesterol … does absolutely nothing to testosterone levels (unless you are an infertile man in which case you may see an improvement).

Shilajit Extract (100mg): Muscle Tech claims that Shilajit extract increases ATP production (basically means more energy during workouts etc) in a similar way to creatine monohydrate. But the evidence for this really isn’t very strong. There does appear to be some evidence that Shilajit increases testosterone production though. A study on infertile men saw a 23.5% increase in testosterone production, though this has not been repeated with fertile men [3].

Boron Citrate (100mg): A pretty decent ingredient really. A 2011 study found that taking 10mg of Boron every day for six days led to an increase in testosterone and a reduction in estrogen [4]. It’s early days, and we’d ideally want a few more studies to back this up, but at the moment Boron is looking like a decent ingredient.

Broccoli Powder (50mg): Diindolylmethane (DIM) is a molecule that is found in certain vegetables belonging to the brassica family. Broccoli is an excellent source of this molecule, as is kale. The main benefit of DIM is that of an aromatase inhibitor. Aromatase is an enzyme that converts testosterone into estrogen, and it is the bane of overweight men. DIM is therefore an excellent ingredient for a natural testosterone booster as it will prevent the loss of testosterone and its conversion into estrogen.

Stinging Nettle Extract (50mg): It is commonly believed that stinging nettle extract can boost testosterone, but this has been disproven by science. A six-month trial involving 558 overweight men found absolutely zero change in testosterone levels compared to the placebo [5]. A dud ingredient.

Velvet Bean Extract (50mg): More commonly known as Mucuna Pruriens, Velvet Bean Extract may actually be able to increase testosterone, though studies have only seen differences in men who were infertile. It can also reduce cortisol in chronically stressed men. As long-term elevated cortisol can impact testosterone, any supplement that lowers cortisol can have a small impact on testosterone.

MuscleTech Test HD Customer Reviews

As with many natural testosterone boosters, we’ve seen a large amount of positive reviews claiming that Test HD has made a huge difference to the reviewers’ lives.

We’ve also seen a large amount of negative reviews saying that the product doesn’t work.

Due to testosterone levels being almost impossible to estimate without blood work, whether you think it works or not is dependent on guesswork.

It’s funny, we’ve reviewed a lot of natural testosterone boosters that have been a LOT worse, but have had much more positive reviews.

This may be the best natural testosterone booster so far, and it has the lowest ratings on both Amazon and Bodybuilding.com.

MuscleTech Test HD Final Thoughts

There are a couple of dud ingredients contained within Test HD, but for the most part this is a surprisingly decent supplement.

The blend of ingredients that can increase testosterone, ingredients that can reduce estrogen, and ingredients that can reduce cortisol is a really good idea.

As with any natural testosterone booster, this will only make a difference to men who have low testosterone levels currently.

If your testosterone levels are already optimal you will have no need for it.

But, considering most men are suffering from low t scores, this is a supplement that can help the majority of men taking it.

The addition of zinc is a clever idea, as it will help combat any overtraining side effects (namely reduced testosterone production thanks to a zinc deficiency).

This really is a good natural testosterone booster.

Well worth giving it a go.
